1 . The public nowadays has a misunderstanding of forest fires, believing that fires should be kept out of every type of forest. Many of us can recall Smoky the Bear's famous warning: “Remember, only YOU can prevent forest fires”. However, that's not always the case. Under the right conditions, and when conducted safely, fire can create many environmental benefits as well as help prevent larger, uncontrollable wildfires.

After a forest fire, many wildlife species will move into recently burned areas to feed on these newly available foods. Some reptiles and amphibians such as the pine (松树) snake prefer forests frequently burned by fire. As Herbert Stoddard put it, “One of the most harmful things modern man has done to birds has been his attempt to exclude fire from fire-type pine forests. Within a few years most forests choke up with bushes, lose their prairie-like vegetation (草原般植被) and can no longer support birds dependent on periodic burning for their food supply and proper cover.”

If you are asked to picture the forest floor, what do you see? Pine needles, cones, leaves, branches might come to mind-all sources of fuel. If these fuel sources build up without any type of removal, the 'fuel load' can lead to fires catastrophic to forests and people alike. In contrast, prescribed fire can be used by forest professionals every couple of years to keep forest fuels at an appropriate and manageable level. They can also minimize the spread of pest insects and disease and remove unwanted tree and plant species. Plus, they can create and maintain important wildlife habitats rich in grasses and promote the growth of trees, wildflowers and other various plants.

Many organizations and agencies work to promote fire on the landscape when and where appropriate. Smokey Bear even has an updated warning: “Only You can Prevent Wildfires,” as the Forest Service has over the last few decades developed policies and procedures to include prescribed fire as a management tool, as well as continuing their work to prevent and fight wildfires.

4 . Thirteen, for me, was a challenging year. My parents divorced and I moved to a new town with my father, far from my old family and friends. I was terribly lonely and would cry myself to sleep each night. To ease my sadness, my father purchased an old horse for me at a local auction. I named him Cowboy.

Cowboy was undoubtedly the ugliest horse in the world. But I didn’t care. I loved him beyond all reasons.

I joined a riding club and suffered rude comments and mean snickers about Cowboy's looks. I never let on about how I felt, but deep inside, my heart was breaking. The other members rode beautiful, registered horses.

When Cowboy and I entered the events where the horse is judged on appearance, we were quickly shown the gate. No amount of preparation and love would turn Cowboy into a beauty. My only chance to compete would be in the speed events. I chose the jumping race.

One girl named Becky rode a big brown horse in the race events. She always won the blue ribbons. Needless to say, she didn't feel threatened when I competed against her at the next show. She didn’t need to. I came in next to last.

The stinging memory of Becky’s smirks made me determined to beat her. For the whole next month I woke up early every day and rode Cowboy five miles to the arena. We practiced running and jumping for hours in the hot sun and then I would walk Cowboy home totally exhausted.

All of our hard work didn’t make me feel confident by the time the show came. I sat at the gate and sweated it out while I watched Becky and her horse charge through the course and finish in first place.

My turn finally came. I put on my hat, rubbed Cowboy’s neck and entered the arena. At the signal, we dashed toward the first fence, jumped it without trouble and raced on to the next one. Cowboy then flew over the second, third and fourth fences like a bird and I turned him toward the finish line.

As we crossed the line the crowd was shocked into silence. Cowboy and I had beaten Becky and her fancy horse by two seconds!

I gained much more than a blue ribbon that day. At thirteen, I realized that no matter what the odds, I'd always come out a winner if I wanted something badly enough to work for it.

1. What does the underlined part “... we were quickly shown the gate.” in paragraph 4 probably mean?
A.We were told how to enter the arena.B.We were shown how to make the horse beautiful.
C.We were removed from the competition early.D.We were told to enter the timed-speed events.
2. Why was the writer not confident of victory?
A.He was an inexperienced rider.B.He believed he was unpopular with the crowd.
C.He had not practiced enough.D.He thought his horse wasn’t as good as the others.
3. What did the writer learn from his experience?

4. What can be a suitable title for the story ?

5 . Many years ago, when we were a young couple with two small children, aged 2 and 4, we were practically impecunious. My in-laws lived from hand to mouth, so we didn’t expect any help from them. My parents lived a great distance away, and I was too ashamed to let them know about our situation.

My husband was trying to earn a living with an old pick-up truck, carrying groceries for local shopkeepers, but it was constantly breaking down. It took almost all the money we had to have it fixed. The truck was also the only means of transportation for us.

We lived in the countryside, and we always used the back door because the driveway led to it. One winter evening, I stepped outside to take a bag of trash to the barrel and almost tripped over something. It was nearly dark, and I had to bend down to see what it was. I could hardly believe my eyes. There sat a large basket loaded with food.

It was heavy, so I called to my husband to carry into the house. Once inside, we discovered two loaves of bread, some butter, several cans of vegetables, a can of orange sauce, and a large turkey. There was so much that I can’t remember it all, but it was everything we needed to fix a wonderful dinner — everything except potatoes.

A little while later I remembered that I hadn’t taken the trash to the barrel. By now it was dark, so I had to turn on the yard light — and that’s when I spotted a small bag of potatoes sitting on the porch.

That dinner was the best I can remember.

We weren’t able to thank our donators, though, because we never found out who had been so generous in helping a struggling young family. Whoever it was, we are forever grateful.

A.Adequate.B.Penniless.C.Harmonious.D.Stubborn.

C.By working as a shop assistant.D.By delivering goods.

6 . The sea could be the food bowl of the future. In Jervis Bay, south of Sydney, seaweed, which is rich in fibre and omega 3, is grown and harvested.

Pia Winberg is a marine scientist who runs Australia's first food-grade fanned seaweed company. Her crop is grown alongside mussels (贻贝)and is used as an additive in pasta (意大利面)and other products.

Seaweed is also raised in large tanks, where it absorbs carbon dioxide waste from a wheat processing factory. The business is small, but could help to reduce the ecological footprint of traditional farming.

“We used ten percent of seaweed instead of wheat in breads and pastas, we've eliminated a million hectares of land, we've eliminated all of the carbon dioxide emissions associated with that, and we've also reduced the pressures on very precious fresh water.” said Pia Winberg.

Spiny sea urchins (多刺海胆虫)are another blue economy resource. They can destroy marine habitats, but a recent competition for environmental start-ups in Australia, saw them not as a pest but a delicacy (美味).

Martina Doblin, CEO of Sydney Institute of Marine Science, said, “By 2050 we will have some ten billion people on the planet, and about half the food they eat will come from the ocean. So, we really do need to pay attention to the way that we manage the blue economy-generating wealth from the ocean but in a sustainable (可持续的)way.”

Farming at sea has its challenges. Infrastructure (基础设施)has to be sound, as do supply chains and biosecurity. But get these things right, and the ocean might just be the next great economic frontier.

1. What is the function of the first paragraph?
A.To lead to the main topic.
B.To describe a new kind of seaweed.
C.Tell how important the food safety is.
D.To explain the meaning of blue economy.
2. What can we learn from what Martina Doblin said in paragraph 6?
A.Ocean exploration has made little progress so far.
B.More and more people will die of hunger in the future.
C.More work is needed for a better use of the natural resources.
D.Sea farming will be a good way to solve the coming world food problem.
3. Which word can be used to describe the author's attitude towards sea fanning?
A.Skeptical.B.Objective.C.Tolerant.D.Negative.
4. Which can be a suitable title for the text?
A.How to Protect the Marine Animals
B.Measures to Develop Blue Economy
C.Farming the Sea for the Future of Food
D.Traditional Farming is Gradually Disappearing

7 . The United States is a nation of car owners. Ninety-five percent of households own a car, and 85 percent of people get to work in one. This lifestyle contributes to congestion on our roads and damages the environment. As autonomous vehicles begin to hit the streets over the next decade or so, it's believed that all this will change.   

Autonomous vehicles will most likely decrease the number and severity of crashes, allow cars to travel more closely together and improve cooperation between vehicles, all of which tend to reduce traffic jams and increase capacity.

However, this future is not assured. To realize the full potential benefits of driverless cars, we will have to act soon to encourage a culture in which transportation is shared. Many people in the automobile industry assume that driverless vehicles will automatically be shared, but there is little evidence that this is true. Most estimates suggest that driverless cars will eventually be only slightly more expensive than traditional cars, which means they'll be within reach of many consumers, so users are not willing to share rides.

If most people are going to buy-in to a shared-ride culture, they need to get a significant benefit. Saving a few dollars off the fare isn't likely to promote the movement dramatically. A better benefit would be knowing that you're going to reach your destination more quickly. The way to guarantee quick passage is to redesign our roads to give priority to ride-sharing autonomous vehicles like building priority lanes. The cost of travel will also be varied based on how efficiently a vehicle uses the roads. Autonomous vehicles carrying multiple people should get higher priority than those carrying one or none at all.

Decision-makers must push for incentives that encourage the most efficient use of our limited roadway infrastructure(基础设施). The autonomous future is rapidly approaching; it is critical that we act now, while the impacts of autonomous vehicles on traffic jams and emissions are still largely within our control.

1. What's the purpose of the first paragraph?
A.To introduce the topic.
B.To tell the severe traffic problem.
C.To prove the necessity of autonomous vehicles.
D.To show the damage of cars to the environment.
2. What can we learn from the passage?
A.Autonomous vehicles worsen traffic jams on roads.
B.Autonomous vehicles are likely to reduce traffic jams.
C.Saving some fares contributes to shared-ride significantly.
D.Many people have ridden autonomous vehicles to avoid traffic jams.
3. Which will be a benefit of sharing autonomous vehicles?
A.To save a large amount of money.
B.To promote the development of science and technology.
C.To redesign roads to prioritize car-shared modes.
D.To allow you to reach your destination much more quickly.
4. Which is the best title for the passage?
A.Driverless Cars Will Make Our Traffic Problems Worse.
B.Autonomous Vehicles Will Make a Difference to Traffic.
C.Decision-makers Should Take Some Measures Quickly.
D.The Current Situation of Cars in the United States is Serious.

8 . Northeastern University in Northeast China's Liaoning Province said it will remove 52PhD students who failed to finish their studies within the permitted study period. One often has been studying for their PhD for 18 years and another two for 17 years, according to an announcement made by the university's College of Information Science and Engineering on Tuesday.

The students were admitted to the college from 2002 to 2012, a list on the college's official website showed. About 78 percent of them have been studying for their PhD at the college for over a decade. The study period for doctoral students in the university is three years, however, and the maximum length of schooling is six years with suspensions included, according to the management rules of the university.

Chinese universities have been seen clearing those postgraduate or PhD students who fail to graduate at the correct time in recent years. Xidian University in Xi'an of Northwest China, for example, removed 33 PhD students in August, some of whom had been studying for 15 years. Yanbian University in Northeast China's Jilin Province announced on November29, 2019, that it would delist 136 graduate students, including 14 PhD students.

A staff member of the university said that some of the students left without telling the school or going through the correct procedures. The difficulties in PhD study and the improving requirements for academic achievements have been found to be the main reasons resulting in students dropping out, experts said. Yang Liu, an associate professor who graduated with a PhD four years ago from a key university in Shanghai, told the Global Times that it is not strange for some PhD students to drop out under the strict academic review process. He also said that some may be scared off by the economic pressure of long-term schooling.

1. What is the permitted study period for a PhD at most?
A.A decade.B.7 years or so.C.6 years.D.Within 3 years.
2. Which of the following might be the major reason for the dropouts?
A.The long term of schooling.B.The increasing requirements for study.
C.The economic pressure of schooling.D.The mixed procedures for leaving universities.
3. What's the best title for the text?
A.The difficulties in PhD study scare off many students
B.Students fail to graduate from their universities
C.University in China's northeast delists over 50 PhD students
D.Chinese University is considering clearing some PhD students
4. Which word best describes the author's attitude to the universities' decision?
A.Objective.B.Worried.C.Critical.D.Hopeful.
